Title: Improvements in and relating to the coating of articles by cathode disintegration
IPC: C23C14/35
Filed: 1938-07-25
Abstract: 501,500. Depositing substances by electric discharge. BERGHAUS, B. July 25, 1938, No. 22004. Convention date, Aug. 14, 1937. [Class 39 (i)] In the coating of articles by cathode disintegration use is made of a cathode which surrounds the articles on all sides. In the apparatus shown the whole of the inner surface 4 of the disintegration chamber 1 may be constructed and connected up as the cathode. The articles 13 to be coated are secured to a conductor 15 introduced in an insulated manner into the disintegration chamber and screened by a metal sleeve 20. The suspension devices are preferably constructed of the material to be disintegrated. The anode voltage may be applied to the conductor 15 whilst the metal sleeve 20 carries a negative voltage with respect to the conductor. Preferably, however, a negative voltage is applied to the conductor 15 whilst the metal sleeve 20 carries a positive voltage and serves as the anode, the articles being surrounded by a glow fringe. In the case of disintegration by alternating current the voltage is applied between the articles to be coated and the disintegration vessel. The disintegration chamber may be surrounded by a heating or cooling jacket and the conductor 15 may be formed hollow so that it may be cooled. If it is desired to disintegrate the cathode material in a glowing state the disintegration chamber may be surrounded in a vacuum tight manner by a second container in which the pressure is reduced to relieve pressure on the wall of the disintegration chamber. The disintegration chamber may be made solid of cathode materials such as iron, copper, nickel, magnesium or aluminium but in the case of expensive materials such as silver, gold, platinum or rhodium, or of materials which have not sufficient strength such as cadmium, beryllium, chromium, titanium, molybdenum, tantalum or tungsten the disintegration vessel may be coated with the materials on its inner wall. The articles may be subjected to a cleaning gas discharge before the disintegration.

Title: Improvements in or relating to apparatus embodying cathode-ray tubes
IPC: H01J29/72
Filed: 1953-08-10
Abstract: 746,777. Cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 10, 1953 [Aug. 13, 1952], No. 22026/53. Class 39 (1). In cathode-ray tube apparatus having a planar target and an electron permeable electrode adjacent to the target and parallel therewith, and means for deflecting the beam in one or more planes over the target there is provided an auxiliary deflecting means between the gun and the main deflecting means to shift the beam parallel to itself and in the plane or planes of deflection to counteract undesired deflection of the beam caused by the field between the target and the electron permeable electrode, and the auxiliary and main deflection means are synchronized by a suitable circuit external to the tube. The auxiliary deflection means may comprise two pairs of plates 17, 19; 18, 20, Fig. 3, cross-connected, or equivalent pairs of coils 38, 39, Fig. 5; correcting members may be provided for one or both directions of deflection. Electromagnetic deflection means and electrostatic correction or electrostatic deflection and electromagnetic correction may be used. The correction may be partial or complete. The undesired deflection is towards or away from the tube axis according as to whether the screen is positive or negative with respect to the electron permeable electrode. In a colour television receiver, Fig. 5, multistrip fluorescent screen 31 is associated with parallel wire grid 33. Auxiliary pairs of coils 38, 39 correct for the deflection at right angles to the grid wires and two further pairs of coils may if desired be provided for correcting for the deflection parallel to the grid wires. The grid adjacent the target may be used for post deflection acceleration; it may be replaced, for this purpose, by one or more annular wall coatings. The target and grid may be inclined to the tube axis. If the luminescent screen is non-conductive it may be associated on either face with a conductive electrode; it may be used for oscillograms or television images. Alternatively there may be a plurality of targets as in a switching circuit. The grid may be replaced by a thin metal foil. In a colour television receiver, the grid divides the image into lines or dots. The auxiliary and main deflection means are connected by a synchronizing circuit comprising cathode-ray tubes, resistors, capacitors, transistors, &c. Correction of the deflection by a multicolour fluorescent screen with non-uniform phosphor strip spacing is stated to be impractical.

Title: An improved hayloader
IPC: A01D87/06
Filed: 1920-07-23
Abstract: 170,131. Fowler, W., and Ewing, M. July 23, 1920. Ratchet and like step-by-step conveyers and elevators.-In hay-loaders comprising rakes which push the hay up a sloping platform, the rakes are mounted on eccentrics on two shafts which are connected by gearing and are driven from the travelling wheels through a countershaft or its equivalent. The wheels 4 are provided with ribs 5 on their treads and drive sprocket-wheels 8 through free-wheel clutches which may be thrown out of operation simultaneously by means of a hand-lever 13.

Title: Improvements relating to braking and steering mechanism for crawler excavators
Inventor: TAWLKS THOMAS HENRY
IPC: B62D55/084
Filed: 1950-09-07
Abstract: 695,472. Vehicle brakes. PRIESTMAN BROS., Ltd. Nov. 8, 1951 [Sept. 7, 1950], No. 22095/50. Class 103 (i). The invention is concerned with drive transmission arrangements for crawler excavators of the type in which the super-structure, comprising the operator's cab, is rotatable on the undercarriage and is concerned particularly with means whereby one or both the track driving sprockets may be locked or disconnected from the drive for braking and steering purposes. As shown in Figs. 1 and 2, the drive is transmitted from a shaft 8, coaxial with the pivot mounting 2 of the superstructure, by bevel wheels 10 keyed to transverse shafts 5 on which are keyed ratchet wheels 11 having square section teeth 12. The ratchet-wheels 11 may be looked against rotation for holding the excavator stationary by means of pawls 13 which are urged by springs 18 into engagement with the teeth. The pawls are, however, held inoperative by a rod 20 pressed downwardly by the pressure on a circular plate 22 extending around the pivot mounting 2 of a roller 27 on the end of an arm 25 operated from a pedal 39 by the excavator driver. The pedal 39 includes a foot-piece catch 44, 41 by which it may be held down to keep the ratchet wheels 11 unlocked. The sprockets 4, which drive the crawler tracks, are secured to sleeves 46 freely rotatable on the shafts 5 which are splined on their inner ends to carry clutch members 47. The clutch members 47 carry a series of pins 48 which project from each face. On the one side they are engageable with holes 49 in the ratchet-members 11 to transmit the drive from the shafts 5 to the tracks 4. On the other side they are engageable with notches 50 in the housing of the bearings 7 to hold the tracks locked with the drive disengaged. Operation of the slidable clutch members 47 is by means of the lever linkage 52, 54, 55 and a shaft 61 passing through the pivot mounting of the superstructure and operated by a hand control 66. Operation of the control 66 has the effect of engaging the clutch member 47 on one side with its respective ratchet-wheel 11 while locking the other clutch member with the fixed notches 50, as is the condition shown in Fig. 5. Due to the slotted pin connection between the lever arm 55 and rods 54 while one track is being driven, it is possible for the other to be either locked by engagement of the pins on the clutch member with fixed notches 50 or free, but not driven, when the clutch member is in neutral position. The excavator will turn in tight or large circles according to either condition. The control lever 66 moves in a gate which is cranked at 69 to prevent it being slammed from one extreme position to the other and thus ensuring time for the pin clutch to engage with its respective ratchet-wheel. In a modified transmission described, the ratchet-wheels are made integral with the track driving sprockets and the clutch mechanism is between the ratchet wheels and the bevel wheels.

Title: Improvements in machines for expanding sheet metal
IPC: B21D31/04
Filed: 1919-09-10
Abstract: 155,032. Expanded Metal Co., Salmon, H., and Booton, H. Sept. 10, 1919. Angular bending; expanding; expanding-dies.-In a machine for expanding metal sheets, previously slit to form parallel strips connected by junctions of uncut metal, expanding is effected by a pair of divergent guides which engage the selvedges of the sheet and enclose portions of the sheet so that only the unenclosed portions can expand, the enclosed portions diminishing as the sheet passes through the guides. The selvedges of the slit sheet are deformed, and the sheet may be forced by the slitting or deforming rolls or both through the guides without the aid of other feeding-means co-acting with the guides. The selvedges are first bent into hooked shape 5 by a pair of rolls 1 provided at opposite ends respectively with segmental internally and externally bevelled flanges 2, 3, Fig. 5. The sheet 4 is then forced into a pair of fixed divergent guides 9 through a guide 6, Fig. 6, having a slot 7 with grooved ends 8 to retain and guide the selvedges. The divergent guides, Fig. 8, which are formed in two parts to provide guide slots 10 and have grooves 11 to retain and guide the selvedges, are tapered from the point of entry of the sheet so that expanding starts from the centre of the sheet. The edges may be straight or provided with steps 90. Pinwheels 12 rotated by chain gear 13 from the deforming-rolls may be used, if desired, to draw off the sheet.
